How do I backup original rom before upgrade
I cooked my own 6.1 ROM a while ago, now I want to try some 6.5 ROMs and see if I like any of them. But I want to keep a copy of my original ROM(which I can not find on my computer now) in case I want to roll back.
How do I back up the rom? (I already backup my contacts, docs, etc. )
Thanks!
